Description

Technical Field

[0001] The present invention belongs to the technical field of permanent magnet synchronous motors, and in particular relates to an integrated variable frequency permanent magnet synchronous motor device. Background Art

[0002] Permanent magnet synchronous motors are widely used in mining equipment due to their small size, high energy density and stable working performance. In order to enable permanent magnet synchronous motors to output stable power under complex working conditions, they are often required to be used in conjunction with frequency conversion control equipment. At present, mining frequency converters are large in size and can achieve "one-to-many" control. They are mostly installed in fixed machine rooms in the form of control cabinets. Therefore, to control permanent magnet synchronous motors in on-site operating equipment, they must be connected through long-distance control lines. However, frequency conversion control signals will be interfered by the external environment during long-distance transmission, affecting the efficiency and stability of the motor.

[0003] In the prior art, the inverter and the permanent magnet synchronous motor are only physically connected, which is bulky and not compact. In addition, the permanent magnet synchronous motor is mostly used in places such as mines, where there is a lot of dust and water vapor in the surrounding working environment. When used for a long time, the dust will adhere to the filter net and block the filter holes, affecting the heat dissipation effect. When the motor is placed in the working environment for a long time, the surrounding water vapor will enter the motor through the vents, causing the internal components of the motor to be corroded by moisture, accelerating the aging and damage of the motor.

[0004] Therefore, we propose a variable frequency permanent magnet synchronous motor integrated device to solve the above problems. Summary of the invention

The connection between the bottom shell 1 and the top shell 2 is fixed by bolts, which is convenient for disassembly and assembly of the bottom shell 1 and the top shell 2, and convenient for cleaning and maintenance of the inside of the bottom shell 1 and the top shell 2. The combination mode of the frequency converter and the permanent magnet synchronous motor is optimized, so that the overall equipment structure is compact, the occupied space is reduced, and the use is more flexible.

[0028] It should be noted that the cross connecting block 16 is fixedly mounted on the lower surface of the rotating rod 801. Through the setting of the cross connecting block 16, when the bottom outer shell 1 and the top outer shell 2 are connected together, the cross connecting block 16 can be smoothly inserted into the upper end of the rotating shaft 15, thereby connecting the rotating rod 801 and the rotating shaft 15 together, and when the rotating shaft 15 rotates, it can smoothly drive the rotating rod 801 to rotate together.

[0029] The upper end of the rotating rod 1 801 is rotatably mounted on the inner top wall of the top outer shell 2, and an intermittent gear 802 is arranged on the circumferential surface of the rotating rod 1 801, and the circumferential surface of the intermittent gear 802 is meshingly connected with a moving frame 803, and a lifting rod 805 is hingedly connected to the upper left end of the moving frame 803 through a hinge rod 804, and a cleaning brush 806 is arranged at the lower end of the lifting rod 805, and the upper end of the rotating rod 1 801 is transmission-connected to the rotating rod 2 807 through a transmission mechanism 7, and the upper end of the rotating rod 2 807 is rotatably mounted on the inner top wall of the top outer shell 2, and a cooling fan 808 is arranged at the lower end of the rotating rod 2 807;

[0030] It should be noted that gear teeth matching the intermittent gear 802 are provided on the front and rear sides of the inner wall of the moving frame 803, which can smoothly mesh with the intermittent gear 802 when the intermittent gear 802 rotates, and then when the intermittent gear 802 rotates to mesh with the inner wall of the rear side of the moving frame 803, the moving frame 803 can move horizontally to the right, and when the intermittent gear 802 meshes with the inner wall of the front side of the moving frame 803, the moving frame 803 can move horizontally to the left, and then under the continuous rotation of the intermittent gear 802, the moving frame 803 can move back and forth horizontally, and then can smoothly drive the lifting rod 805 and the cleaning brush 806 to move vertically back and forth through the hinge rod 804, and the number of gear teeth on the surface of the intermittent gear 802 occupies less than a quarter of the circumference of the intermittent gear 802, so that when the intermittent gear 802 meshes with the inner rear side of the moving frame 803, the intermittent gear 802 will not mesh with the inner wall of the front side of the moving frame 803, avoiding jamming.

[0031] The transmission mechanism 7 includes a pulley 1 701, a transmission belt 702 and a pulley 2 703. The pulley 1 701 is connected to the pulley 2 703 through the transmission belt 702. The two pulleys 1 701 are respectively arranged on the circumferential surface of the motor shaft 6 and the circumferential surface of the rotating rod 2 807. The two pulleys 2 703 are respectively arranged on the circumferential surface of the rotating shaft 15 and the circumferential surface of the rotating rod 1 801. The arrangement of the bottom transmission mechanism 7 can make the motor shaft 6 drive the rotating shaft 15 to rotate through the bottom transmission mechanism 7 when the permanent magnet motor body 3 is working, and then the rotating shaft 15 drives the rotating rod 1 801 to rotate, so that the rotating rod 1 801 smoothly drives the rotating rod 2 807 and the cooling fan 808 to work through the top transmission mechanism 7, so that when the permanent magnet motor body 3 is working, the cooling fan 808 can perform heat dissipation work synchronously, and the heat dissipation effect is better;

[0032] The top outer shell 2 is provided with an opening and closing mechanism 9, which includes an installation box 901, which is provided on the left inner wall of the top outer shell 2. The middle part of the rotating rod 801 is rotatably installed in the installation box 901. The installation box 901 is provided with a turbine blade 902, and the turbine blade 902 is provided on the circumferential surface of the rotating rod 801, so that when the rotating rod 801 rotates, the turbine blade 902 can be driven to rotate. A lifting block 90 is provided above the turbine blade 902. 3. The lifting block 903 is movably installed inside the installation box 901 through a spring 905, and the upper end of the lifting block 903 is located outside the upper end of the installation box 901. The upper side wall of the lifting block 903 is provided with an annular lifting plate 904, and the upper part of the annular lifting plate 904 is solid, and the lower part is provided with a ventilation hole. The circumferential surface of the top outer shell 2 is provided with an air inlet 13. The annular lifting plate 904 is slidably installed inside the top outer shell 2, and the upper part of the annular lifting plate 904 is located at the air inlet 13;

[0033] It should be noted that when the turbine blades 902 rotate, an upward airflow can be formed inside the installation box 901, so that the airflow pushes the lifting block 903 upward, and then the lifting block 903 can push the annular lifting plate 904 to move upward, so that the part of the annular lifting plate 904 with the filter holes moves to the air inlet 13, and then the outside air can enter the outer shell through the filter holes of the annular lifting plate 904, forming air circulation and achieving heat dissipation, and the setting of the spring 905 can, when the turbine blades 902 no longer rotate and the airflow is no longer generated inside the installation box 901, the spring 905 pulls the lifting block 903 downward back to the initial position, and then the lifting block 903 pulls the annular lifting plate 904 back to the initial position, so that the solid part of the upper part of the annular lifting plate 904 moves to the air inlet 13, and the air inlet 13 is closed to prevent external dust and water vapor from entering the shell. Inside, it pollutes and corrodes the electrical components, thereby increasing the service life of the device; it should also be noted that because the air inlet 13 is annular in design, the internal annular array of the air inlet 13 is provided with several fixed plates for connecting the upper and lower parts of the top outer shell 2 to avoid the upper and lower parts of the top outer shell 2 from being separated. The setting of the fixed plates will divide the air inlet 13 into several vents, and each vent is provided with a group of lifting rods 805 and a cleaning brush 806. The upper ends of several groups of lifting rods 805 are provided with annular connecting plates for forming several groups of lifting rods 805 into a whole, and then when the moving frame 803 moves horizontally left and right, the lifting rod 805 at the left end can be smoothly driven to move vertically through the hinged rod 804, and then the lifting rod 805 at the left end drives other lifting rods 805 to move vertically together through the annular connecting plate at the top.

[0034] Positioning rods 906 are provided on both the front and rear sides of the upper end of the lifting block 903, and the lower ends of the two sets of positioning rods 906 are provided with connecting rods 10, and the right end of the connecting rod 10 is provided with an annular sealing plate 11, and the lower surface of the annular sealing plate 11 is provided with a sealing block 12, and a plurality of sealing blocks 12 are provided, and an air outlet 14 matching the sealing block 12 is opened at the lower end of the bottom outer shell 1, and when the device is not used, the sealing block 12 is plugged into the inside of the air outlet 14 to close the air outlet 14 to prevent the outside from Dust, water vapor and the like enter the outer shell to contaminate and corrode the electrical components, and to improve the service life of the device, a fixing rod 19 is provided on the inner bottom wall of the bottom outer shell 1, and two fixing rods 19 are provided, and the lower ends of the two groups of positioning rods 906 are respectively sleeved on the inside of the two fixing rods 19, and a slide groove 18 is provided on the left side of the inner top wall of the top outer shell 2, and two groups of slide grooves 18 are provided, and slide rods 17 are slidably installed inside the two groups of slide grooves 18, and the lower ends of the two groups of slide rods 17 are respectively connected to the left and right ends of the movable frame 803.

[0035] When the present invention is in use, the permanent magnet motor body 3 and the inverter body 4 are energized with an external power supply, and the permanent magnet motor body 3 and the inverter body 4 are started. When they work, they will emit a large amount of heat. The heat dissipation fins 5 arranged on the surface of the permanent magnet motor body 3 and the inverter body 4 can conduct part of the heat to the outer shell, and then conduct it to the outside world;

[0036] At the same time, the permanent magnet motor body 3 works to drive the motor shaft 6 to rotate, and the rotation of the motor shaft 6 drives the pulley 1 701 at the bottom to rotate, so that the pulley 1 701 at the bottom drives the pulley 2 703 at the bottom to rotate through the transmission belt 702, so that the pulley 2 703 drives the rotating shaft 15 to rotate, and the rotating shaft 15 rotates through the cross connecting block 16 to drive the rotating rod 1 801 to rotate, and the rotating rod 1 801 rotates to drive the turbine blade 902 to rotate, so that an upward airflow appears inside the installation box 901, and the airflow can push the lifting block 903 upward, so that the lifting block 903 drives the annular lifting plate 904 and the fixed plate 904 to rotate. The positioning rod 906 moves vertically upward. When the lifting block 903 rises to a certain height and the elastic force of the spring 905 is in a balanced state with the air flow inside the installation box 901, the lifting block 903 no longer moves upward. At this time, the lower part of the annular lifting plate 904 with the filter hole moves upward to the air inlet 13. The positioning rod 906 drives the annular sealing plate 11 and the sealing block 12 to move upward through the connecting rod 10, so that the sealing block 12 moves upward from the inside of the air outlet 14. At this time, the inside of the bottom outer shell 1 and the top outer shell 2 can circulate air with the outside world to achieve rapid heat dissipation.

[0037] When the rotating rod 1 801 rotates, it also drives the intermittent gear 802 and the upper pulley 2 703 to rotate. The upper pulley 2 703 rotates and drives the upper pulley 1 701 to rotate through the transmission belt 702, and then drives the rotating rod 2 807 and the cooling fan 808 to rotate, so that the cooling fan 808 blows air downward, so that the air inside the shell flows downward and carries the heat transmitted from the cooling fins 5 and is discharged from the air outlet 14. At the same time, the outside air enters through the air inlet 13 to realize air circulation, and the inside of the shell is quickly cooled. At the same time, the intermittent gear 802 When the rotation engages with the inner wall of the rear side of the moving frame 803, the moving frame 803 is driven to move horizontally to the right. When the rotation engages with the inner wall of the front side of the moving frame 803, the moving frame 803 is driven to move horizontally to the left, so that the moving frame 803 can move back and forth horizontally. Then, the lifting rod 805 and the cleaning brush 806 are driven to move vertically back and forth through the hinge rod 804. The vertical reciprocating movement of the cleaning brush 806 can clean the outer surface of the annular lifting plate 904. Then, in a dusty environment, dust is prevented from adhering to the outer surface of the annular lifting plate 904 to block the filter holes and affect the ventilation and heat dissipation effect.

[0038] When the device is not used, the permanent magnet motor body 3 stops working, so that the rotating rod 801 stops rotating, and then the turbine blades 902 stop rotating, and the upward airflow is no longer generated inside the installation box 901. The lifting block 903 is restored to its initial state under the action of the spring 905, and then the lifting block 903 drives the annular lifting plate 904 and the positioning rod 906 to move downward to the initial state. The annular lifting plate 904 moves downward so that the solid part of its upper part occupies the air inlet 13, thereby closing the air inlet 13. The positioning rod 906 moves downward to the initial state to drive The annular sealing plate 11 and the sealing block 12 are moved back to the initial position, so that the sealing block 12 is inserted into the air outlet 14 to close the air outlet 14. When the device is not in use, the vent of the device can be isolated from the outside world to prevent dust and water vapor from entering the device through the vent to contaminate and corrode electrical components, thereby improving the service life of the device. The bottom outer shell 1 and the top outer shell 2 can also be separated by removing the bolts at the connection between the bottom outer shell 1 and the top outer shell 2, thereby facilitating cleaning and maintenance of the components inside the bottom outer shell 1 and the top outer shell 2.
